A new article that came out recently in Josei Seven indicates that Jin and Meisa are having some troubles. Brief translation as follows:
Since the birth of their daughter last September, they stayed in Okinawa, and with the help of Meisa's family they were able to have dates and enjoy life. In December, the family of three moved back to Tokyo and Meisa started her work in the new drama. On the surface Jin has been really supportive of Meisa's work and is taking care of the baby being the domestic parent. However according to a friend of Meisa's family, their way of life is completely different than in Okinawa, and they prioritize Meisa's work. However Jin also wants to do his own thing.
Also their 600,000/month luxury apartment in Tokyo has been infamous in their neighbourhood. Their neighbour claims that "at night, when the surroundings are all quiet, there is one apartment where the lights are on, with many fashionable young people coming in and out, and sometimes the speakers are turned up..... Hard to believe there is a baby in that household."
Meisa herself traveled with the baby alone in mid January back to Okinawa and left her in the care of Meisa's mother..... Everytime she went to Okinawa in the past it has been in the company of Jin but this time she went alone. She was also alone when she came back for the baby a month later.
An insider commented "Even though Jin currently has no job and supposed to be taking care of the household, he hasn't made any changes. He treats going out with his friends and partying as his priority. Even though he has said he likes kids and wants to be a good father, he's still too young, and not suited to be a father right now."
Meanwhile Meisa's mom has quit her job and moved to Tokyo to help them take care of the child.
